What is the function of thrust washers in an engine?

Thrust washers are small but vital components that control the end-play of the crankshaft. They sit between the crankshaft and the engine block to prevent the crankshaft from moving too far forward or backward, which is crucial for maintaining proper oil clearances and preventing damage.

Should I replace thrust washers during a standard oil change?

No, thrust washers are internal engine components and are typically replaced only during a major engine overhaul or when addressing specific issues related to crankshaft end-play. They are not part of routine maintenance like oil changes.
